Abstract (en)

A time period for which an ineffective operation is performed during an excavation work is reduced. A work machine includes a vehicular body, a running wheel rotatably attached to the vehicular body, a work implement operable with respect to the vehicular body, an operation apparatus for operating the running wheel and the work implement, and a controller that controls an operation by the work machine. The controller determines that slip-during-excavation which refers to slip of the running wheel with respect to the ground is occurring during the excavation work based on an operation command value output from the operation apparatus and outputs a signal relating to working of the work implement.
